Abstract

The invention relates to the technology of manufacturing electrical machines and can be used in electrical engineering. The purpose of the invention is to save electrical steel. In the tape 1, grooves of slots 2 and 3 are cut through the middle, bottom, Spitz and upper parts of the groove. Then half of the grooves are bent along opposite lines of the groove wall with the tooth in opposite directions, positioning them on the teeth. Then the cuttings are cut along the lines of intersection of the groove wall with the tooth in opposite directions, located on the teeth. Between . the valleys of each slot and the opposite edge of the belt are molded by a chute. On the other two uninterrupted strips with a thickness corresponding to the height of the rear part of the strip, they are formed by drawing a groove similar to the tape grooves. Fasten three strips, aligning them with grooves with each other, weld, obtaining a three-layer tape, which is then aligned, forming a spiral. 9 nl. W

Phys. 1

The invention is referred to the technology of manufacturing electrical machines and can be used in the electrical industry.

The purpose of the invention is to save electrical steel ..

FIG. 1 shows a tape with a-; chennpu and halves of the grooves; FIG. 2 is a view A of FIG. one; in fig. 3 - tape with rounded teeth, with a wavy surface in the zone of rm; in fig. 4 - airborne B in FIG. 3; in fig. 5 is a section | B-B in FIG. 3; in fig. 6 - three clamps - Foam tapes with gutters in body color; in fig. 7 - section GG on |) u. 6; in fig. 8 is a view of D in FIG. 6; in fig. 9 - part of the coil of the magnetic Yit.pipe after alignment of the glands.

I The manufacturing process of the magnetoprodes of electric machines is carried out as follows. ; In the tape 1 of the ferromagnetic material, half of the grooves 2 are cut through the lines AB-BC-DE-EF and 3 through the lines BI-GH-HL. those. in the middle, bottom, slotted and upper parts of the groove with interruption of the edge 4 and do not break the connection of the groove halves with the teeth 5. Then cut the halves of the grooves along the lines of the groove of the wall of the groove with the tooth in opposite directions their jja teeth Then, the ijro cuttings of the intersection of the groove wall wall with the Jag in opposite directions are bent in opposite directions. on the teeth, and get

strip, 6 with flat teeth 7. Between the depressions 8 of each slot and the opposite edge 9 of the tape are formed by drawing a groove 10. On two other continuous strips 11 and 12 with a width corresponding to the height of the outside part of the strip 6; molded. drawing a groove 10 similar to the grooves of the strip 6.

Then fasten the strips 6, 11 and 12, aligning them with grooves with each other, weld the strips at points 13, to obtain a three-layer tape 14, align the tape, to obtain a spiral 15.

Claims (1)

Invention Formula A method of manufacturing magnetic conductors of electrical machines from a continuous tape, including slot cutting, forming grooves in the front zone between teeth, obtaining a helix by welding, characterized in that, in order to save electrical steel, each slot is cut through the middle, bottom, slotted and the upper part of the groove m, then bend the cuttings along the lines of intersection of the wall of the groove with the tooth in opposite directions, positioning them on the teeth, before forming the grooves, on the sides of the belt on both sides impose two tapes of thicknesses hydrochloric, LRG appropriate height portion and spiral po.luchayut alignment troughs simultaneously in three tapes.
